OVEN-GRATE.

SPECIFICATION forming part of Letters Patent No. 434,970, dated. August26, 1890*.

Application filed ovember 9, 1887. Serial No. 254,714. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN H. ALLYN, a citizen of the United States,residing at Whitesborough, in the county of Oneida and State of NewYork, have invented a new and useful Improvement in Grates for the Ovenand iVarming-Oloset of a Range or Stove, of which the following is aspecification.

My invention relates to improvements in extensible shelves or grates forthe oven and warming closet of ranges and stoves.

It has for its object to provide devices which will securely locate,guide,and support such shelves; and it consists in the mattershereinafter specified and pointed out.

In the accompanying drawings, Figure 1 is a perspective view of the ovenof a range or stove with the door removed and a corner cut away, and ofa shelf or grate with its guides, lugs, slides, and sides attached tothe floor of an oven and drawn out. Fig. 2 is a perspective view of aguide, a lug, aslide provided with a stop and recess and side providedwith stops, the guide, slide, and side being shown disconnected. Fig. 3is a perspective view of a shelf-frame having corner-pieces attached.Fig. 4: is an elevation of the inner ends of the guides, lugs, slides,sides, and back of the shelf or grate, and Fig. 5 is a side elevation ofa guide, lug, and floor of a range or stove.

The oven it contains the shelf B, consisting of a frame provided with agrating or net work of wire. It is or may be provided at its backcorners with angled pieces J, the lower ends of which are fastened tothe sides and backof the shelf, the back parts J of the upper ends beingfolded over to receive and hold the edge of an upper shelf (indicated bydotted lines) and the front upper parts J turned down at right angles tosupport an upper shelf in a horizontal position when required.

The guides O consist of angled strips of metal extendingfrom the frontcorners to about the center of the sides of the floor of the oven, andthe upper edges of their up right parts are folded over, forming groovesto receive the slides E. The horizontal parts of these constitute waysfor the horizontal parts of the slides E, and the inner ends of theguides O are held in position by lugs D entering holes in the floor ofthe oven.

The slides E consist of angled strips of metal, which extend from thefront nearly to the back of the oven. Their upright parts are foldedover, forming grooves for the edges of the upright parts of the sides H,and their horizontal parts constitute ways for the horizontal parts ofsaid sides, and are provided with stops F and recesses G for controllingand limiting their movement. These stops project to the outer side ofthe slides and are adapted to engage the inner ends of the guides. Thesides H also consist of angled strips of metal and extend from the frontto the back corners of the grate or shelf, the edges of the uprightparts being adapted to move in the grooves of the slides E, and theirhorizontal parts being provided with stops I on their under side. Theymove on the slides E, their movement being controlled or limited by thestops I, formed on or attached to sides H, and adapted to engage theends of the recesses G. The sides H may be constructed to hold the shelfat any desired height above the floor of the oven.

The lugs D consist of pieces of metal having each an end bent andfastened to the guides O, substantially as shown. The bent ends areadapted to enter holes suitably located in the floor of the oven.

The shelf 13, together with the slides E and the guides C, may be placedin position in the oven by elevating the front of the shelf to an angleof about forty degrees, thereby allowing the lugs D to enter the holesin the floor of the oven, and then lowering the grate to a horizontalposition. guides may be readily removed upon raising the front endssufficiently. The shelf B, when drawn nearly out is sustainedhorizontally in a plane above and parallel with the floor of the oven Aby the slides E and guides C. The front ends of the slides extend out toabout the center of the sides H, and are prevented from leaving them andlosing the sup port of the guides O by the stops F coming in contactwith the inner ends of the guides The shelf slides and C. The sides Hand the shelf are prevented from leaving the oven and losing the supportof the slides E by the stops I coming in contact with the front ends ofthe recesses G. When returning the shelf into the oven, the stops I comein contact with the inner ends of the recesses G and return the slidesE.

Having thus described my invention, what I desire to secure by LettersPatent, is-

1. In combination with an oven having a floor provided with openings,guides having bent projections adapted to be entered in said openings,slides held movably in said guides, and a shelf movably supported insaid slides, substantially as set forth.

2. In combination, an oven, guides removably secured to a wall of theoven, slides adapted to move in the guides and provided with stopsadapted to engage the guides, and a shelf having sides held movably inthe slides, substantially as set forth.

3. The. main shelf provided with cornerpieces of angular form incross-section, the top of one side of each piece being bent inwardly tosustain a supplementary shelf, and the top of the other sides beingsimilarly bent in a higher plane to embrace the top of the shelfcombined with said supplementary shelf, substantially as set forth.
